System and method for setting a wear allowance of an electrical contactor

A method for setting a wear allowance of an electrical contactor comprising:

• inserting a plunger rod within a solenoid plunger that is disposed within an upper housing portion of the electrical contactor, wherein the upper housing portion includes a pair of stationary mating contacts;
• turning the plunger rod to rotate downward through the solenoid plunger along a longitudinal axis towards a plunger base of the electrical contactor, wherein the plunger base includes a pair of moving mating contacts;
• raising the plunger base upward along the longitudinal axis towards the upper housing portion of the electrical contactor, wherein the plunger base includes a threaded insert that is configured to accept a lower threaded portion of the plunger rod as its rotated and threaded to the threaded insert, wherein the plunger base is raised based on the downward rotation of the plunger rod and the pair of moving mating contacts are configured to move upwards towards the pair of stationary mating contacts;
• and
• setting the wear allowance of the electrical contactor based on a mating of the pair of moving mating contacts with the pair of stationary mating contacts, wherein the mating of the pair of moving mating contacts and the pair of stationary mating contacts occurs as the plunger rod is further rotated within the threaded insert of the plunger base.
